摘要： In order to provide a cascade heat pump with which a large temperature lift can be provided with high efficiency, a cascade heat pump comprising n stages where n≥2 is proposed. Each of the n stages has a heat pump with a coolant inlet, a first coolant outlet, and a second coolant outlet. Each heat pump has a hot side and a cold side and a flow divider to divide a coolant flow entering the coolant inlet between the hot side and the cold side. The first coolant outlet of the heat pump of each stage i, where i=1 . . . n−1, is connected to the coolant inlet of the heat pump of a subsequent stage i+1. The second coolant outlet of the heat pump of at least one subsequent stage i+1 is connected by a recirculation line to the coolant inlet of the heat pump of a preceding stage.

摘要： A refrigeration cycle apparatus includes a refrigerant circuit in which a compressor, a first heat exchanger, an expansion mechanism, and a second heat exchanger are connected by pipes. The first heat exchanger includes a first refrigerant passage and a second refrigerant passage that share a plurality of fins with each other and provided in parallel in the refrigerant circuit. The apparatus further includes a high-and-low-pressure switching mechanism which is located on an inlet side of the second refrigerant passage of the first heat exchanger in flowing of refrigerant in an operation in which the first heat exchanger functions as a condenser, and which performs switching between flow directions of the refrigerant. The apparatus further includes a refrigerant blocking mechanism located on an outlet side of the second refrigerant passage of the first heat exchanger in the flowing of the refrigerant in the operation, and which blocks the flowing of the refrigerant.

摘要： A mechano-caloric stage includes an elongated outer sleeve. An elongated inner sleeve is disposed within the elongated outer sleeve. A pair of pistons is received within the elongated inner sleeve. Each of the pair of pistons is positioned at a respective end of the elongated inner sleeve. The pair of pistons are moveable relative to the elongated inner sleeve. A mechano-caloric material is disposed within the elongated inner sleeve between the pair of pistons. The mechano-caloric material is compressible between the pair of pistons.

摘要： A heat pump includes a first portion for evaporating a working fluid at a first pressure, for compressing the evaporated working fluid to a second, higher pressure, and for liquefying the compressed working fluid within a liquefier, and a second portion for compressing liquid working fluid to a third pressure, which is higher than the second pressure, for evaporating the working fluid compressed to the third pressure, for relaxing the evaporated working fluid to a pressure, which is lower than the third pressure, so as to generate electrical current, and for liquefying relaxed evaporated working fluid within the liquefier.

摘要： When starting a cooling operation mode from a non-operating mode, the blower device of the indoor unit from which the start command is originated is operated. When starting a heating operation mode from a non-operating mode, the blower device of the indoor unit from which the start command is originated is operated after the heat medium temperature becomes equal to or greater than a preconfigured temperature.

摘要： A four-process cycle is disclosed for a Vuilleumier heat pump that has mechatronically-controlled displacers. Vuilleumier heat pumps that use a crank to drive the displacers have been previously developed. However, mechatronic controls provides a greater degree of freedom to control the displacers. The four-process cycle provides a higher coefficient of performance than prior cycles in the crank-driven Vuilleumier heat pump and those previously disclosed for a mechatronically-driven Vuilleumier heat pump.

摘要： A management device manages plural heat pump systems to bring a total amount of energy consumed by the heat pump systems closer to a target value. The management device includes a request transmitting unit, a consumption information receiving unit, a database, and a learning unit. The request transmitting unit transmits requested values of energy consumption to each of the heat pump systems. The consumption information receiving unit receives actual values of energy consumption from each of the heat pump systems. The database stores response characteristics of consumers having each of the heat pump systems with respect to the requested values of energy consumption. The learning unit learns the response characteristics and reflects learning results based on past records of responses of each of the consumers with respect to the requested values of energy consumption in the database.

摘要： An induced groundwater flow closed loop geothermal system provides safety associated with closed loop geothermal systems (e.g., no mixing of surface water, closed system fluid, and groundwater) and efficiency associated with open loop geothermal systems (e.g., increased heat transfer provided by groundwater flow). A heat exchanger connected to an external system is located in a hole in a geological formation. The hole has a depth below where groundwater is located. A fluid from the external system is routed through the heat exchanger. A pump is utilized to induce groundwater flow from the geological formation, across the heat exchanger and back to the geological formation to enable thermal transfer between the fluid and the groundwater and the groundwater and the geological formation. A casing may be located in the hole to provide structural support and grouting materials may be used to fill space around the casing enabling a groundwater flow path.
